Thirsty cities? The supply, management, and perception of water in Byzantine North Africa

Cities of North Africa experienced a long occupation up to the late 7th c. CE. Despite numerous studies on Late Antique urbanism, no systematic investigation of urban hydraulics has been carried out so far. This paper examines the hydraulic topography of three cities in the Byzantine period (ca. 6th c. CE): Leptis Magna (Tripolitania), Sbeitla (Byzacena), and Timgad (Numidia). This analysis assesses to what extent Late Antique societies managed the cities’ water supply by maintaining or transforming preexisting hydraulic networks. It considers the continuity of aqueducts and the reorganization of water networks, the state of hydraulic management and technology, and the perception of water resources. The hydraulic networks inherited from the Early Roman period were to some extent preserved, although greatly adapted to new concerns for security and new technical and environmental constraints, illustrating the resilience of Late Antique societies.
